What are the requirements for the Zoologist NPC to move in Terraria?

The Zoologist is a unique NPC in Terraria who sells various items related to animals, critters, and pets. To get the Zoologist to move in, you need to meet a specific requirement tied to the Bestiary, a feature introduced in the 1.4 update. The Bestiary tracks information about enemies, critters, and other creatures you encounter in the game. The Zoologist will move in once you have filled at least 10% of the Bestiary. This means you need to encounter and defeat or interact with a variety of creatures to unlock her as an NPC.

To start filling the Bestiary, you need to explore different biomes and encounter creatures. Each time you defeat or interact with a new creature, its entry in the Bestiary is updated. The Bestiary tracks how many times you have killed or interacted with each creature, and it also provides information about their drops and behavior. The Zoologist will not move in until you have filled at least 10% of the Bestiary, so you need to focus on encountering as many different creatures as possible.

One effective strategy to fill the Bestiary quickly is to explore multiple biomes. Each biome has unique creatures, so visiting different areas will help you encounter a wide variety of enemies and critters. For example, the Forest biome has creatures like bunnies, squirrels, and slimes, while the Desert biome has vultures, antlions, and scorpions. The Underground and Cavern layers also have unique creatures like bats, skeletons, and jellyfish. By exploring these areas, you can quickly fill up the Bestiary.

Another important tip is to use items that increase spawn rates, such as Battle Potions and Water Candles. These items will make more creatures appear, allowing you to encounter new enemies faster. Additionally, using a Lifeform Analyzer can help you track rare creatures that you might otherwise miss. The Lifeform Analyzer is a useful accessory that displays the names of nearby creatures, making it easier to find and defeat them.

When preparing to fill the Bestiary, it is important to have the right equipment. A good weapon and armor set will help you defeat enemies quickly and efficiently. If you are playing as a melee character, a sword or spear is a good choice. For ranged characters, a bow or gun will work well. Magic users can use spells like the Water Bolt or Demon Scythe. Summoners can use minions to help defeat enemies. Having a variety of weapons and armor will make it easier to handle different types of creatures.

One common mistake to avoid is focusing too much on one biome. While it is important to explore each biome thoroughly, spending too much time in one area can slow down your progress. Instead, try to rotate between different biomes to encounter a wider variety of creatures. Another mistake is ignoring critters. While they may not seem important, critters like bunnies, squirrels, and birds also count towards the Bestiary. Make sure to interact with them to fill up the Bestiary faster.

Advanced techniques for filling the Bestiary include using biome-specific items and events. For example, using a Blood Moon or Solar Eclipse event can spawn rare creatures that are difficult to find otherwise. These events can help you fill up the Bestiary quickly. Additionally, using biome-specific items like the Jungle Spores or Desert Fossil can help you craft items that increase spawn rates or provide other benefits.

Resource requirements for filling the Bestiary are relatively low. You mainly need weapons, armor, and potions to help you defeat enemies. However, having a good supply of healing items like Healing Potions and food can help you stay alive during battles. It is also a good idea to have a variety of tools like a pickaxe, axe, and hammer to help you explore different biomes and gather resources.

In terms of class and equipment considerations, any class can fill the Bestiary effectively. However, some classes may have an easier time than others. For example, ranged characters can attack enemies from a distance, making it easier to defeat them without taking damage. Magic users can use spells to quickly defeat groups of enemies. Summoners can use minions to attack enemies while they focus on exploring. Melee characters may have a harder time with ranged enemies, but they can still be effective with the right equipment.

Specific examples of creatures to focus on include slimes, which are common in many biomes, and bats, which are found in caves. Critters like bunnies and squirrels are also important to interact with. Rare creatures like the Unicorn in the Hallow biome or the Wyvern in the Sky biome can help fill up the Bestiary quickly. By focusing on these creatures and using the strategies mentioned above, you can quickly fill up the Bestiary and get the Zoologist to move in.

In conclusion, getting the Zoologist to move in requires filling at least 10% of the Bestiary. This involves exploring different biomes, encountering a variety of creatures, and using items and strategies to increase spawn rates. By following these steps and avoiding common mistakes, you can quickly fill up the Bestiary and unlock the Zoologist as an NPC.
